27 PCS Magnet Rainbow Cube Rock Stone Fidget Toys for Adults, Magnet for Whiteboard Office Map Kitchen, Replacement Magnet with Fiber Case for Ferrite Putty, Magnetic Game

Cubes were slightly smaller than I expected though I'm sure they were described accurately. As mineral products they were slightly irregular, which I did expect. The natural variation of their iridescent surface coating is the essence of their charm. I wanted to use them to stack into different multi-cube shapes for a photography project, but they are not very suited for that. As weak bipolar magnets, any pair sticks together well, but arranging them into precise multi-level forms is difficult. I will try using putty or tape to hold them in the arrangements I want. They seem best suited to be elegant and extremely high-quality refrigerator magnets. The set I received came in a nice carrying case with three spare cubes. They are very high quality, but not suited for precision projects. Anyone purchasing them as a gift for children should note that hematite is brittle and should be handled carefully.

Got these for my 10 year old grandson and he loved them. He had a hard time putting them down to open his other gifts!Would caution if there are little ones that put things in their mouths.

It is an excellent addition to the fidget activities I have for my students. Thank you

Beautiful little magnetic blocks, great carrying case too.

Have purchased three different styles from different sellers. The are the worst of the three. They chip and break really easily. Go with the round marble style if you’re undecided.

Gave these to my grandkids, they were so excited but let down because the magnets don't stick good (their words). I checked them out and they barely had any magnetic pull. Bummer 😞

these are weak magnets, pick them all up and they fall under their own weight

These barely hold together, let alone to a metallic surface.
